Frequently asked questions about aluminum I beams

Are aluminum I beams as strong as steel?

Is aluminum stronger than steel? Many grades of aluminum are considered high-strength and can even compare to certain steel alloys.

However, when comparing samples of the strongest aluminum alloy and steel alloy of the same size, steel is typically the stronger material.

What are aluminum I beams used for?

Aluminum I beams are commonly used in structural applications where a high strength-to-weight ratio and corrosion resistance are essential.

Are aluminum I beams expensive?

The price of aluminum I beams depends on factors such as alloy type, size, surface treatment, and market aluminum prices.

While aluminum is generally more expensive than steel per unit, it offers significant long-term cost savings due to its lightweight nature, corrosion resistance, and low maintenance requirements.

How do I choose the right size and alloy for my project?

We offer a wide range of standard and custom sizes to meet your specific needs!

Whether you need 4-inch, 6-inch, 8-inch I beams or specially customized dimensions, we provide the perfect solution.

Our aluminum I beams are made from high-strength, corrosion-resistant alloys such as 6061-T6, 6063, 5083, and 5086—ensuring long-lasting reliability and performance.
